One of the things that has long intrigued me is how people of different political and ideological attitudes can look at the same set of facts and interpret them in entirely different ways.
For example, it’s no secret to readers of this site that I’m a conservative who views a whole range of issues–the size and reach of government, taxes, entitlement programs, education, immigration, health care, abortion, America’s role in world affairs, and so forth–in a particular way. One of my long-time friends, a man who has played a significant role in my Christian faith, is a liberal who disagrees with me on virtually everything having to do with politics. He’s smart, informed, and has integrity. We’ve had good, rich conversations over the years. Yet there’s very little common political ground we share.
We simply look at the same issues, the same events, in a fundamentally different way.
I thought about my friend while reading Jesse Norman’s outstanding biography Edmund Burke: The First Conservative. In the second half of the book, devoted to Burke’s political philosophy, Norman invokes the Muller-Lyer illusion, a benchmark of human visual perception in which two lines of the same length appear to be of different lengths, based on whether the fins of an arrow are facing inward or outward.
